        <p>
      <span class="emphasis"><em>insnum</em></span> -- instrument number. Equivalent to p1 in a score <a class="link" href="i.html" title="i Statement (Instrument or Note Statement)"><em class="citetitle">i statement</em></a>. <span class="emphasis"><em>insnum</em></span> must be a number greater than the number of the calling instrument.
    </p>
        <p>
      <span class="emphasis"><em><span class="quote">“<span class="quote">insname</span>”</span></em></span> -- A string (in double-quotes) representing a named instrument.
    </p>
        <p>
      <span class="emphasis"><em>iwhen</em></span> -- start time of the new event. Equivalent to p2 in a score <a class="link" href="i.html" title="i Statement (Instrument or Note Statement)"><em class="citetitle">i statement</em></a>. <span class="emphasis"><em>iwhen</em></span> must be nonnegative. If <span class="emphasis"><em>iwhen</em></span> is zero, <span class="emphasis"><em>insum</em></span> must be greater than or equal to the p1 of the current instrument.
    </p>
        <p>
      <span class="emphasis"><em>idur</em></span> -- duration of event. Equivalent to p3 in a score <a class="link" href="i.html" title="i Statement (Instrument or Note Statement)"><em class="citetitle">i statement</em></a>.
    </p>
        <p>
      <span class="emphasis"><em>ip4, ip5, ...</em></span> -- Equivalent to p4, p5, etc., in a score <a class="link" href="i.html" title="i Statement (Instrument or Note Statement)"><em class="citetitle">i statement</em></a>.

        <h2>Performance</h2>
        <p>
      <span class="emphasis"><em>schedule</em></span> adds a new score event. The arguments, including options, are the same as in a score. The <span class="emphasis"><em>iwhen</em></span> time (p2) is measured from the time of this event.
    </p>
        <p>
      If the duration is zero or negative the new event is of MIDI type, and inherits the release sub-event from the scheduling instruction.
